01 - Preheat oven to 350°F. Grease and flour two 8-inch round cake pans, ensuring thorough coverage for easy release.
02 - Whisk together flour, baking powder, baking soda, and salt in a medium bowl until uniformly blended.
03 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, approximately 3-4 minutes. Add eggs one at a time, incorporating fully before each addition. Stir in vanilla extract.
04 - Alternate adding flour mixture and milk to the creamed butter mixture, beginning and ending with flour. Mix until just combined, taking care not to overmix.
05 - Divide batter evenly between prepared pans. Bake for 22-25 minutes until a wooden toothpick inserted into the center emerges clean.
06 - Allow cakes to cool in pans for 10 minutes before carefully turning out onto wire racks. Cool completely before assembly to prevent frosting melting.
07 - Beat butter until smooth and creamy. Gradually incorporate powdered sugar, vanilla extract, salt, and sufficient milk to achieve spreadable consistency.
08 - Keep first cake round intact for the bunny face. Cut second cake round in half to create two oval ears, then trim remaining center portion into a bow tie shape.
09 - Position face, ears, and bow tie on a large serving platter, arranging to resemble a bunny face with bow tie below.
10 - Spread a thin layer of frosting over all cake pieces to seal in crumbs. Refrigerate for 20 minutes to set the crumb coat.
11 - Apply final layer of buttercream frosting to entire cake surface. Press shredded coconut generously over frosting to create furry texture.
12 - Tint small portion of coconut with pink food coloring. Gently press pink coconut onto inner sections of ear pieces for dimension.
13 - Place fondant or marshmallow details on ears. Position jelly beans for eyes and nose. Add any additional facial features as desired.
14 - Store covered at room temperature for up to 2 days, or refrigerate for up to 4 days for extended freshness.
